Description

Technical Field

[0001] The present invention relates to the technical field of diaper production, and particularly relates to a composite sticker processing device for diaper production. Background Art

[0002] Diapers are products that can be discarded after single use, and are divided into two types for infants and adults. Therefore, the user groups of diapers are mainly infants and adults. The adult users of diapers are usually patients who are inconvenient to move, unable to take care of themselves, or bedridden for a long time. Because these people maintain a fixed posture for a long time, the diapers they use need to have high liquid absorption capacity, dryness on the main body surface, no side leakage, and no easy reverse osmosis. They are made of materials such as non-woven fabric, toilet paper, fluff pulp, superabsorbent polymer resin, PE film, and rubber bands.

[0003] During the production process of diapers, it is necessary to bond the surface coating layer, absorbent core layer, and bottom cloth in the diaper together and then perform pressing. The commonly used pressing devices on the market usually use the pressing force between two rollers to paste them. Although this method saves manual fitting and improves efficiency, it has the following problems: 1. It is easy to shift during the production process, resulting in misalignment and material waste; 2. The needle is easy to stick to the composite sticker material during the punching process, causing material jamming; 3. The heat is uneven during the embossing process, making the composite sticker material unable to be fully bonded; 4. The risk is relatively high because during pressing, it is necessary for workers to send the diaper close to the pressing roller to be rolled in for pressing, reducing the safety of the workers' hands, and there are often cases where the hands touch the pressing roller; 5. When the material is being transported, the tension is not easy to control, and it is easy to loosen, resulting in wrinkles in the material and poor pressing effect; 6. It is impossible to perform on-line detection on the pressed diapers, etc. Summary of the Invention

The punching mechanism 3 includes a support rod 301 with a convex needle 303 and a roller 302 matching the support rod 301. The roller 302 is provided with a needle groove matching the convex needle 303. A cylinder 304 is fixedly connected to the support rod 301, and the cylinder 304 is connected to the frame 1. The support rod 301 is driven to move up and down by the expansion and contraction of the cylinder 304 to punch the composite sticker material on the roller 302;

[0049] An embossing mechanism 4 arranged opposite to the punching mechanism 3. The embossing mechanism 4 includes a pre-pressing member 401 and an embossing member 402 installed on the frame 1. The pre-pressing member 401 includes a pre-pressing rotating shaft 4011 installed on the frame 1.

[0051] As a preferred embodiment of the present invention, it may further have the following additional technical features: The deviation rectifying member 202 includes upright columns 11 symmetrically arranged on the frame. An deviation rectifying roller 12 is installed between the two upright columns 11. The deviation rectifying driving member 203 includes a deviation rectifying motor 15 installed on the side of the upright column 11. The output end of the deviation rectifying motor 15 is connected to a worm 14. A turbine 13 is meshed with the worm 14. A threaded rod 34 is threadedly connected to the turbine 13. A connecting block 35 is fixedly installed at the end of the threaded rod 34. The connecting block 35 is fixedly connected to the end of the deviation rectifying roller 12. The threaded rod can move up and down through the top of the upright column. Bearings are installed at the bottom end of the turbine and on the left and right sides of the worm, and its installation method can be realized according to the prior art, which will not be elaborated one by one in this embodiment. Moreover, the deviation rectifying detecting member 201 includes a guiding rod 16 installed on the frame. A deviation rectifying mounting seat 17 is installed on the guiding rod 16. A deviation rectifying sensor 18 is installed on the deviation rectifying mounting seat. The deviation rectifying sensor 18 moves left and right on the guiding rod 16 according to the width of the composite patch material and is fixed.

[0052] Thus, during the winding process of the composite patch material, the composite patch material passes through the C-shaped opening of the deviation rectifying sensor. The deviation rectifying sensor 18 detects the position of the edge of the composite patch material, picks up the edge position deviation signal, and then transmits the position deviation signal to the controller for logical operation. Then, a control signal is sent to the deviation rectifying motor 15. The deviation rectifying motor 15 works to control the rotation of the worm 11, thereby driving the turbine 13 to move up and down, and further driving the deviation rectifying roller 12 on the turbine to move up and down to adjust the angle of the composite patch material, so as to correct the position of the composite patch material, ensure that the composite patch material moves in a straight line in the center, and avoid quality problems such as incomplete bonding caused by the easy deviation of the composite patch material during the production process.

[0053] In this embodiment, bearings 19 are respectively arranged between the two ends of the inner hole of the roller 7 and the outer circle of the roller shaft 6. One side of the bearing 19 is fixedly connected to a mounting seat 20, and the other side is connected to a movable retaining ring 21. A bolt 22 connecting to the roller shaft 6 is arranged on the movable retaining ring 21. The end of the mounting seat 20 is fixedly connected to the inner wall of the roller 7. Thus, it is convenient to disassemble and install the pressure roller.

[0054] In this embodiment, the heating element 10 includes an inlet rotary joint 1001 threadedly connected to the roller shaft 6. One end of the inlet rotary joint 1001 is communicated with the inlet end of the spiral flow channel 8, and the other end is connected to a first centrifugal pump 1002 through a pipeline. The input end of the first centrifugal pump 1002 is connected to a liquid storage tank 1003 through a pipeline. The other end of the liquid storage tank 1003 is connected to an outlet rotary joint 1005 through a pipeline, and the outlet rotary joint 1005 is communicated with the outlet end of the spiral flow channel 8. A heater 1004 is installed on the liquid storage tank 1003. Thus, by starting the heater 1004, the heated grease in the liquid storage tank 1003 is heated. Then, the heated grease is injected into the spiral flow channel 8 of the pressure roller 4021 through the first centrifugal pump 1002, and the grease is recycled in the pressure roller 4021 and the liquid storage tank 1003 under the action of the first centrifugal pump 1002, ensuring that the composite material is evenly heated during the embossing process to meet the temperature requirements of lamination and ensuring the stability and consistency of the material during the lamination process.

[0055] In this embodiment, the pressure roller 4021 includes a first pressure roller 4021a and a second pressure roller 4021b that matches the first pressure roller 4021a. A driving motor 23 is installed at one end of the first pressure roller 4021a, and a first main gear is connected to the other end. A first driven gear is engaged with the first main gear, and the first driven gear is rotationally connected to the second pressure roller 4021b. The rotating shaft of the driving motor 23 is connected to the input shaft of a speed reducer 24, and the output shaft of the speed reducer 24 is connected to the roller shaft of the first pressure roller through a coupling 25. The driving motor and the outlet rotary joint are located on the same side of the roller shaft 6. Thus, by starting the driving motor 23, the first pressure roller 4021a and the second pressure roller 4021b are driven to rotate, realizing the automatic operation of embossing the composite material passing between the two rollers and ensuring the production quality of the product.

[0056] In this embodiment, the embossing mechanism 4 further includes a cooling roller 403. A straight flow channel 26 and a double-headed spiral flow channel 27 that intersect and communicate with each other are provided inside the cooling roller 403. The straight flow channel 26 is connected to a second centrifugal pump 28 through a rotary joint. The input end of the second centrifugal pump 28 is connected to a coolant storage tank 29, and the coolant storage tank 29 is communicated with the straight flow channel 26 through a pipeline and a rotary joint. Thus, cold water is circulated and injected into the cooling roller body through the rotary joint to cool the cooling roller, and then the composite material wound around the cooling roller is cooled, avoiding overheating of the composite material during winding, which may cause product quality problems or dangerous accidents.

[0057] In this embodiment, it further includes a detection mechanism 30, which includes a camera 3001 and a thickness gauge 3002 installed on the frame 1. The camera 3001 is used to detect surface defects of the composite patch, and the thickness gauge 3002 is used to detect the thickness of the composite patch. The thickness gauge 3002 includes slide rails symmetrically installed above and below the frame, and thickness sensors are movably installed on the slide rails. Thus, by fixing the thickness sensors on the slide rails, they can move left and right, and there is one sensor above and below respectively. The composite patch passes through the gap between the two thickness sensors, and the thickness sensors move left and right, enabling continuous detection of the thickness of various positions of the composite patch. And in this embodiment, by reasonably selecting and using the thickness gauge, accurate measurement of the thickness of various composite patches and objects can be achieved, providing strong support for production and quality control.

[0058] In this embodiment, it further includes a feeding roller 31 and a winding roller 32, and tension sensors for detecting the tension of the feeding roller and the winding roller are installed on both the feeding roller 31 and the winding roller 32. Thus, it is convenient to detect the tension of the detection device and avoid product quality problems caused by excessive or too small tension.

[0059] This embodiment further includes a control mechanism, which is electrically connected to the tension sensors of the feeding roller 31 and the winding roller 32 and a driving member (such as a motor), and the control mechanism is also electrically connected to the deviation rectifying mechanism 2, the punching mechanism 3, the embossing mechanism 4, and the detection mechanism 30, and is used to control the working states of the deviation rectifying mechanism 2, the punching mechanism 3, the embossing mechanism 4, and the detection mechanism 30, so as to realize the automatic production of diapers. The control mechanism includes a controller, a display screen, a control switch, a power supply, etc. The circuit connection thereof and the circuit connection with each mechanism of this processing device can be realized according to the existing technology, and will not be elaborated one by one in this embodiment.

[0060] Embodiment 2

[0061] Such as Figures 9 - 10As shown in the figure, the difference between this embodiment and Embodiment 1 is that: it further includes a buffer mechanism 33 installed between the pre-pressing member 401 and the embossing member 402. The buffer mechanism includes a cylinder 3301 installed on the frame 1. The output end of the cylinder 3301 is connected to a bracket 3302. A lower guide roller 3303 is installed on the bracket 3302. An upper guide roller 3304 that matches the lower guide roller 3303 is arranged above the lower guide roller 3303. The upper guide roller 3304 is connected to the frame 1; and the upper guide roller 3303 and the lower guide roller 3304 are arranged in an interleaved manner. Thus, after the composite patch is pressed, the drive motor 23 is rotated in the reverse direction, and the bracket 3302 and the lower guide roller 3303 on the bracket are driven to move downward by driving the cylinder 3301. When the composite patch is retracted backward to a proper position, the drive motor 23 is rotated in the forward direction, and the cylinder 3301 is started to drive the bracket 3302 and the lower guide roller 3304 on the bracket to move upward, so that the composite patch is subjected to secondary pressing, thereby improving the pressing quality, ensuring that the composite patch is not easily separated from or fall off the core body, and ensuring the production quality of the diaper.

[0062] The working principle of the present invention: When in use, the pasted diaper composite patch is placed in the feeding roller 31, the control mechanism is started, the control motor drives the feeding roller 31 to feed, and the deviation correction mechanism 2 and the tension sensor are used to detect the deviation and tension of the composite patch. When the deviation correction sensor detects that the edge of the composite patch deviates from the preset value, the position deviation signal is transmitted to the controller for logical operation, and then the deviation correction motor 15 is controlled to work, the worm 11 is rotated, so as to drive the turbine 13 to move up and down, and further drive the deviation correction roller 12 on the turbine to move up and down, adjust the angle of the composite patch, so as to correct the position of the composite patch and ensure that the composite patch moves in a straight line in the middle; then it enters the punching mechanism 3, and the telescopic movement of the cylinder 304 drives the support rod 301 to move up and down, and punches the composite patch on the supporting roller 302; then it enters the embossing mechanism 4, and the first pressing roller 4021a and the second pressing roller 4021b are used to perform automatic embossing operation on the composite patch passing through between them, and the cooling roller 403 is used to cool down the composite patch wound around the cooling roller, so as to avoid overheating of the composite patch when it is wound up, and further cause product quality problems or dangerous accidents, and ensure the production quality of the product; finally, after cooling, the surface of the composite patch is detected by the camera 12, and the thickness of the composite patch is detected by the thickness gauge 13, so as to realize the automatic production of the diaper and effectively avoid the phenomenon that the hand touches the pressing roller.
